'lhe hopperjitself comprises a pair of sides W and 1;. united at' thetopmost part by ['10 angliheanis li. 13. 13. at the hark liy hra es ll.14. and ahthe forward portion by plateS' his 15 and 16, a sliding bottomconsisting in the movable gate 20 being preferably employed, whichlatter slides between guideways' 21 and 22, aflixed to the inner sidesof each of the side plates 10 and 12. I refer also to form the bottomportion of t e hopper inclined, as shown in the plate 16 and slidinggate 20, thus facilitating the removal of the brick by gravity u on theraising of the gate 20. At the forwar and uppermost end of the frontplate 15, is a flan e 25, adapted to rest against the faceof the iln andconstituting a lip or plate over which the rows of brick to betransferred from the kiln to the hopper will slide. This flange alsotakes up the pressure p or thrust of the entire hopper against the kiln,and determines the lowermost course of brick which are to be moved intothe kiln. By having the gate 20 also inclined, I may have the sameelevated a short distance and thus control the chuting or dumping of thebrick when discharging from the hopper. Suitable eyes or rings 27, 27,are formed in the side plates 10 and 12, to receive the supportingcables 3, 3, these being spaced and thus providing a four pointsuspension. To operate the gate 20, I provide pneumatic cylinders 30,30, on the outside of theside plates 10 and 12, being at tached to saidside plates by flanges 31, 31, and with the piston 33 pivoted at 34 to aprojecting lug 36, which is attached to the gate 20, said lug traversinga slot 3:? in the side plates. \Vith these pistons 30 at each side, andoperated simultaneously, the gate 50 will be actuated to open or closeat will, upon proper manipulation of the pneumatic force through theconduits 37, 37, which preferably extend to the point of control on thecrane.

In order to effect the mechanical separation and removal of the brickfrom the kiln to the hopper, I provide power actuated reciprocating armsor a framelike device, being adapted to extend over the topmost row ofthe brick to be removed and thereupon to have a brick engagingwedge-like member extend downwai'dl back of the desired plurality ofrows 0 brickprefcrably of a width substantially equal to that of thehopper, and thereupon draw the arms or frame hackwardly, simultaneouslydrawing the brick engaged by the wedge into the hopper over the flange25. -Aftcr such a loading action, the hopper can he moved laterally andthe loading action repeated, or can be louered for a desired distanceand the pie determined number of rows being i'ciiioved at a time, againengaged and drawn into the hopper, until the latter is full.

in order to clfcct this separation of the to he removed and the drawingof the same inwardly. I prepare a pair of [)HOII matic cylinders 40. 40,on each side of the hopper, which cylinders are attached to the outsideof the. side plates 10 and 12, respectively, by flanges ll, 41, boltedthereto. These cylinders contain a piston attached to a rod 44 and thereciprocation of the piston is controlled by a pair of conduits 45,

45, also leading to the one point of control. The rods 44 extend throughguides 46, and extend a suflicieiit distance forwardly of the hopper togive, together with the stroke of the cylinders, a substantialreciprocating movement in advance of the flange 25. These arms areunited at their outward or forward ends by a cross-bar 48, which crossbar carries a pair of guides 49, 49, in which a vertically slidingwedgelike member 50, is adapted to slide, a tongue and groove connectiontherefor 51, 51, or other suitable means, being employed. In order tomove this vertically sliding wedge 50, I attachthereto a pair ofprojecting lugs 51, 51, which are pivoted at 52, 52, to the piston rod53, 53, of a pair of pneumatic cylinders 55, The reciprocation of thepiston in this cylinder is controlled by conduits 56, 56,

also leading to the same point of control as,

the others.

lhe operation of the apparatus will be readily understood. The hopperhaving been swung into desired position, adjacent the uppermost tiers orcourses of layers of brick, with the flange 25 near the lowei'nio wlayer or course of brick to be drawn in the hopper, and with thewedgememher Q in its uppermost position, which wou carry the bottom partsubstantially Hus, with the lower portion of the rods 44, and cross-bar48 the operator actuates the cylindeis 40 to extend or push outwardl tothe extreme forward limit. If desired t is position of the arms andcross-bar can be made and utilized as a means for lowerin andpositioning the hopper on the brick to e re.- moved. As herein shown,the apparatus is designed for removing a maximum of three courses at atime, but can, of course, be employed to remove one or two courses,dependiiig upon the distance downwardly which the wedge 50 is moved.lVith the apparatus in position against the face of the kiln, and ifdesiicd, inclined somewhat, rocking about the flange 25 as a pivot,lifting the bottom portions of the device so that the brick will slidethcreinto, rather than drop, the opera tor then :ictuates the cylinders55, which act to force downwardly the wedge 50, compressing the spacedbrick together some what. substantially as shown in the three top rowsof Fig. l. 'lhese cylinders can be controlled so that the wedge 5U willextend downwardly the depth of one course of brick. of two courses, orof tlirvin as illustralcd. and the capacity of simlar appartus l'illl heincreased to as iniivvouiscs as is doomed advisable. llic dcsircdllllllllltl' and courses of brick to In; moved being thus sep Ill aratedfrom the rest of the kiln, thereupon Lhe cylinders are actuated to drawthe rods 44 inward or liark'vvardly, thus simultaneously moving, drawingand transferring the rows of brick engaged by the edge into the hopper.'lhereupon tln' :fppa-ratus may )0 shifted laterally while maintained atlhe same height and with the flange 25 sliding in contact with [he faceof flu: kiln, the operalor meanwhile having actuated the cylinders toraise the wedg \Vhrn in the new position the i'\'liilll1'l's 1U are theniu-tnaled to more the rods 44, qosslmr and wedge forwardly, intoposition for reartualion of the wedge .50 lo separalc and removiasm-vessi-ve plurality .of brick.
